Do I have to eat more if I exercise more?

The balance between eating and exercising will depend on what your goals are.  If you are increaing your exercise to lose weight, a deficit will still be needed.  When you fill out the health information, it will determine your current calorie usage and give you specifics from there.  You will need to create a healthy gap of calories in vs calories out in order to lose weight and logging your food is a very good idea at this point so you can see exactly what is going on.

If you are increasing your exercise, but need to maintain your weight, you will need to make sure that there is not a gap between calories in vs calories out.  At this point you may need to supplement a little extra to make up the difference.

If you are increasing your exercise to gain weight, such as to gain muscle--then you will definately need to increase your calorie count to keep up with the extra building.  Again this is a great time to see how many calories you are burning and how many you need to consume in order to reach your goal.  Food logging is an excellent way to track this and stay on the right path so that you make the proper gains and reach your overall outcome.

Absolutely. The more active you are, the more fuel your body will require to recover after a workout and to sustain your energy levels throughout the rest of your day. You will also need more fuel to support your immune and metabolic systems throughout the day when you’re upping the exercise.

When you exercise your body must utilize fuel stores that are provided by eating a balance diet of carbohydrates, fat and proteins. When we eat, the food is broken down in to useable units of energy. This energy is stored in our body so that it can be used to exercise or perform normal activities of daily living. The more intense you exercise the more energy you will use. So, generally speaking you need to eat more food to replace lost energy.
